Two longtime friends, Moon-Ho (Yoo Ji-Tae), a college lecturer in art, and Hyun-Joon (Kim Tae-Woo), a struggling filmmaker, both have a weakness for Sun-Hwa (Sung Hyun-Ah). Hun-Joon used to go out with her and when he left for a trip to the United States, Moon-Ho stepped in. Now, with Hun-Joon back in South Korea and Moon-Ho safely married, they track her down once more.
He tells the story of two friends, Mun-ho (Yu Ji-tae, the enemy of Oldboy) and Hyeon-gon (Kim Tae-woo), who find themselves after a gap of several years and spend a few days together. Hyeon-gon just returned from America, where he hoped to become a successful filmmaker. Returning as a failure, he visits his friend Mun-ho, who gave up his artistic efforts years ago in return for the safety of marriage and art education at a university. It is immediately clear that there is tension and jealousy between them, and soon the conversation turns to Seon-hwa (Seong Hyeon-a), a woman whom both met years ago. After each of them have their own private flashbacks, they decide to go visit it. The rest of the movie is the Hong classic - uncomfortable clashes, drunken confessions and sexual misconduct - though not exactly as we are accustomed to. Although not as rewarding as other characteristics, woman is the future of man, proof again is unparalleled when it comes to honestly exposing the weaknesses of the male psyche, particularly with regard to women, relationships and sex.
